Hi, I discovered a video that Is-F in 2008 compared to RS4 and M3 Coupe, I didn’t want to keep that from you:IS-F vs M3 vs RS4 Conclusion of the comparison: The IS-F accelerates better, slows better, is better in handling and the best overall package The tester doesn’t get out of the swarm anymore, but maybe the video was shot by Lexus himself
